virtuoso Posted June 19, 2020 Share Posted June 19, 2020 (edited) I want to choose Shadow mask: "none" with crt-geom-deluxe, so how do I edit the crt-geom-deluxe.json ? "input": [ { "sampler": "mpass_texture", "target": "internal1" }, { "sampler": "mask_texture", "texture": "bgfx/chains/crt-geom/aperture_1_2_bgr.png", "selection": "Shadow mask" }, { "sampler": "blur_texture", "target": "blur" } ], Solved... "none.png". Edited June 19, 2020 by virtuoso Quote Link to comment Share on other sites More sharing options...
Wally Posted March 3, 2021 Share Posted March 3, 2021 (edited) Hi guys, I have a strange issue. While Arcade 64 displays the shader OK (CRT GEOM HQ), running the games using the regular mame.exe (229) does not! Everything is in the same folder I have a vertical.ini and horizont.ini Both Arcade64 and mame.exe TATE the vertical games OK (so mame.exe does indeed process the both ini files). The problem is the shader Here is my vertical.ini in case someone spots something Thank you # # CORE ROTATION OPTIONS # rotate 1 ror 0 rol 1 autoror 0 autorol 1 flipx 0 flipy 0 # # CORE SCREEN OPTIONS # brightness 0.95 contrast 1.1 gamma 0.7 effect none # # OpenGL-SPECIFIC OPTIONS # glslpath glsl gl_forcepow2texture 0 gl_notexturerect 0 gl_vbo 1 gl_pbo 1 gl_glsl 1 gl_glsl_filter 1 gl_glsl_sync 0 glsl_shader_mame0 "CRT Geom HQ Vertical" glsl_shader_mame1 none glsl_shader_mame2 none glsl_shader_mame3 none glsl_shader_mame4 none glsl_shader_mame5 none glsl_shader_mame6 none glsl_shader_mame7 none glsl_shader_mame8 none glsl_shader_mame9 none glsl_shader_screen0 none glsl_shader_screen1 none glsl_shader_screen2 none glsl_shader_screen3 none glsl_shader_screen4 none glsl_shader_screen5 none glsl_shader_screen6 none glsl_shader_screen7 none glsl_shader_screen8 none glsl_shader_screen9 none # # DIRECT3D POST-PROCESSING OPTIONS # hlsl_enable 0 hlslpath hlsl hlsl_prescale_x 4.5 hlsl_prescale_y 3.75 hlsl_preset -1 hlsl_write hlsl_snap_width 1440 hlsl_snap_height 900 shadow_mask_alpha 0.150000 shadow_mask_texture crt_shadow_mask.png shadow_mask_x_count 320 shadow_mask_y_count 240 shadow_mask_usize 0.375 shadow_mask_vsize 0.25 curvature 0.15 pincushion 0.0 scanline_alpha 0.5 scanline_size 1.0 scanline_height 1.0 scanline_bright_scale 1.0 scanline_bright_offset 0.0 scanline_jitter 0.0 defocus 0.0,0.0 converge_x -0.3,0.0,0.3 converge_y -0.3,0.0,0.3 radial_converge_x 0.0,0.0,0.0 radial_converge_y 0.0,0.0,0.0 red_ratio 1.0,0.0,0.0 grn_ratio 0.0,1.0,0.0 blu_ratio 0.0,0.0,1.0 saturation 1.0 offset 0.0,0.0,0.0 scale 1.0,1.0,1.0 power 1.0,1.0,1.0 floor 0.01,0.01,0.01 phosphor_life 0.0,0.0,0.0 # # BLOOM POST-PROCESSING OPTIONS # vector_bloom_scale 0.3 raster_bloom_scale 0.17 bloom_lvl0_weight 1.0 bloom_lvl1_weight 0.21 bloom_lvl2_weight 0.19 bloom_lvl3_weight 0.17 bloom_lvl4_weight 0.15 bloom_lvl5_weight 0.14 bloom_lvl6_weight 0.13 bloom_lvl7_weight 0.12 bloom_lvl8_weight 0.11 bloom_lvl9_weight 0.10 bloom_lvl10_weight 0.09 Edited March 3, 2021 by Wally Quote Link to comment Share on other sites More sharing options...
rom116 Posted July 20, 2021 Share Posted July 20, 2021 Hi everyone. So I have been trying to replicate the MAME core (retroarch) shader for CRT Geom. It looks fantastic in retroarch but the stand alone MAME is much better. I've been messing with BGFX and their version of CRT Geom doesn't look the same. The scanlines seem to be running vertically rather than horizontally and the screen is very, very dark. I have try Derek Moore's (Youtube tutorial on HLSL) settings but his version of MAME is .174 and I'm on .226 and they ini file doesn't seem to have much of an effect. Does anyone have a setup on a more recent version of mame with good scanlines working? Quote Link to comment Share on other sites More sharing options...
SimonLev Posted January 22, 2022 Share Posted January 22, 2022 Great post! So good to know about this. Personally I've gone for the hq4x setting which looks great on a big LCD TV Quote Link to comment Share on other sites More sharing options...
davidgrohl Posted October 24, 2022 Share Posted October 24, 2022 Hi all, thanks to this topic I enabled CRT effect. I'm using this shader: bgfx_screen_chains crt-geom-deluxe I would like to increase the curvature a little bit. How can I do this? Quote Link to comment Share on other sites More sharing options...

Assuming you're using stand-alone MAME... Start MAME and check that you have HLSL turned on. You need this ON to see the slider for quadric distortion (see below). Go to Configure Options, Video Options, and set HLSL = On. Press Escape a couple time to get back to the main screen. Start a game, like Bubble Bobble (bublbobl). Once loaded, press Tab and select Slider Controls. Arrow down to Quadric Distortion Amount. Use left and right arrows to change it to how you like it. Write that number down because it won't [permanently] save anywhere. Exit the game and MAME. Next you need to save that number to an INI configuration file in MAMEs "ini" subfolder. Because of how MAMEs order of precedence works when loading configuration files, you want to put that number in the last INI file that loads. Which is the game specific INI file (#9 and 10 on the list) that you would need to create. In this case, "bublbobl.ini". You'd need to create that for every game you want the curvature. As an option, (a little less work) you can edit the Monitor type INI files (#6 on the list). vector.ini for vector monitors, raster.ini for CRT raster monitors. The 2 more common. These are located under ..MAME/ini/presets/. The value you want to change in those is distortion. Change "0.0" to the number you came up with earlier. Save and close the file(s). Play games. 1 Quote Link to comment Share on other sites More sharing options...
